Halloween is a festival that takes place on October 31. In the United States children wear costumes and masks and go trick-or-treating. Many of them carve jack-o'-lantens out of pumpkins. Fortunetelling and storytelling about ghosts and witches are popular activities.
The main Halloween activity for children is trick- or-treating. Children dress in costumes and masks and go from door to door saying "trick or treat".
Jack-o'-lanterns are hallowed-out pumpkins with face carved into one side. Most jack-o'-lanterns contain a candle inside.
Fortunetelling is an important part of Halloween.
